The above described features and advantages of the present invention will be more apparent from the following description.

1A is a top plan view of a touch sensing panel according to an embodiment of the present invention, and FIG. 1B is a cross-sectional view taken along line I-I of FIG. 1A. Referring to FIG. 1A and FIG. 1B , the touch sensing panel 100 of the present embodiment can be fabricated as a touch screen for use in a variety of electronic equipment, such as a tablet (tablet). Personal computer), laptop, smart phone, and arcade game.

The touch sensing panel 100 includes a plurality of first sensing strips 110 , a plurality of second sensing strips 120 , a substrate 130 , and an insulating layer 140 . The substrate 130 may be a transparent substrate such as a glass plate or a sapphire substrate. The substrate 130 has a flat surface 132, and the first sensing strips 110, the second sensing strips 120, and the insulating layer 140 are disposed above the plane 132. Therefore, the first sensing strip 110 , the second sensing strip 120 and the insulating layer 140 are all located on the same side of the substrate 130 .

These second sensing strips 120 are located below the first sensing strips 110 and contact the plane 132. The insulating layer 140 is disposed between the first sensing strips 110 and the second sensing strips 120 and covers the plane 132 and the second sensing strips 120. Therefore, these second sensing strips 120 will be positioned between the substrate 130 and the insulating layer 140. In addition, the material of the insulating layer 140 may be an insulating material such as tantalum oxide or tantalum nitride, and the insulating layer 140 may be transparent.

These first sensing strips 110 are juxtaposed to each other, and these second sensing strips 120 are juxtaposed to each other. The first sensing strips 110 and the second sensing strips 120 are staggered with each other, so that the first sensing strips 110 and the second sensing strips 120 are different in orientation. Taking FIG. 1A as an example, the orientation of the first sensing strips 110 is substantially perpendicular to the orientation of the second sensing strips 120. The orientation of the first sensing strips 110 is generally perpendicular to the extending direction of the second sensing strips 120.

In the embodiment of FIG. 1A, the extending direction of the second sensing strip 120 may be the horizontal direction X1, and the extending direction of the first sensing strip 110 may be the vertical direction X2. However, in other embodiments, the extending direction of the second sensing strip 120 may also be the vertical direction X2, and the extending direction of the first sensing strip 110 may also be the horizontal direction X1. Therefore, the extending direction of both the first sensing strip 110 and the second sensing strip 120 shown in FIG. 1A does not limit the present invention.

The structure of both the first sensing strip 110 and the second sensing strip 120 is similar. In detail, each of the first sensing strips 110 includes a plurality of first sensing electrodes 112 and a plurality of first traces 114, and each of the second sensing strips 120 includes a plurality of second sensing electrodes 122 and more The second trace 124. In addition, the first sensing electrodes 112 of the same first sensing strip 110 and the first traces 114 are arranged in a row along the vertical direction X2, and the second sensing of the same second sensing strip 120 The electrode 122 and the second traces 124 are arranged in a row along the horizontal direction X1.

Each of the first traces 114 is connected between two adjacent first sensing electrodes 112, and each of the second traces 124 is connected between two adjacent second sensing electrodes 122. In detail, each of the first traces 114 has a pair of first side edges S1 opposite to each other, and the first side edges S1 connect the first sensing electrodes 112. Each of the second traces 124 also has a pair of second side edges S2 opposite each other, and these second side edges S2 also connect the second sensing electrodes 122.

Since the first sensing strips 110 and the second sensing strips 120 are staggered with each other, the first sensing strips 110 partially overlap the second sensing strips 120. In detail, as seen from FIG. 1A, each of the second traces 124 overlaps with one of the first traces 114, so the second traces 124 correspond to the first traces 114. However, each of the second sensing electrodes 122 does not overlap with any one of the first sensing electrodes 112, as shown in FIG. 1A.

In addition, the touch sensing panel 100 may further include a protective layer 150 , and the protective layer 150 comprehensively covers the first sensing strips 110 and the insulating layer 140 to protect the first sensing strips 110 . The material of the protective layer 150 may be the same as the material of the insulating layer 140. For example, the material of the protective layer 150 may be an insulating material such as tantalum oxide or tantalum nitride, and the protective layer 150 may be transparent.

It should be noted that the protective layer 150 is a selective component of the present invention and is not an essential component. Therefore, in other embodiments, the touch sensing panel 100 may not include any protective layer 150. In addition, the touch sensing panel 100 illustrated in FIG. 1A is drawn on the premise that the protective layer 150 is omitted, and thus the first sensing strip 110 illustrated in FIG. 1A is drawn in a solid line.

When the touch sensing panel 100 is used, the user can control the touch sensing panel 100 by using a stylus or a finger. When the stylus or the finger contacts the protective layer 150 or contacts the insulating layer 140 and the first sensing strip 110, the capacitance of the first sensing strip 110 and the second sensing strip 120 corresponding to the stylus or the finger The value will change, and the touch sensing panel 100 can control the electronic device based on the changed capacitance value, such as the cursor displayed on the mobile screen. As such, the user can use the touch sensing panel 100 to operate the electronic device.

Since the touch sensing panel 100 can be used to form a touch screen, the first sensing electrodes 112 and the second sensing electrodes 122 can each be a plurality of transparent conductive layers, and the first traces 114 and The second traces 124 may each be a plurality of transparent wires. The material of the transparent conductive layer and the transparent conductive wire is, for example, Indium Tin Oxide (ITO) or Indium Zinc Oxide (IZO). .

However, it should be noted that even if the touch sensing panel 100 is used to make a touch screen, the first traces 114 and the second traces 124 are not necessarily all without affecting the display quality. Transparent wire. For example, all of the first traces 114 and all of the second traces 124 may be metal lines. Alternatively, some of the first traces 114 and some of the second traces 124 are metal lines, and the remaining first traces 114 and second traces 124 are transparent conductors.

In addition, it is worth mentioning that the touch sensing panel 100 can be used not only as a touch screen but also as an opaque touch input device, such as an electronic sketch pad or It is the touch pad of a notebook computer. Therefore, the substrate 130 can also be an opaque substrate, and the first sensing electrodes 112 and the second sensing electrodes 122 can be a plurality of metal layers.

In this embodiment, each of the first traces 114 has an opening H1, and the second trace 124 is located directly below the opening H1. In the same first trace 114, the opening H1 is located between these first side edges S1. When the openings H1 are viewed from above (as shown in FIG. 1A), it is known that the shapes of the openings H1 are closed patterns, and the shape of the opening H1 shown in FIG. 1A may be rectangular. Therefore, the wall of the opening of the opening H1 does not connect any of the first side edges S1, that is, the opening H1 does not extend from any of the first side edges S1.

It should be noted that although each of the first traces 114 shown in FIG. 1A has an opening H1, in other embodiments, only one or at least two of the first traces 114 may have an opening H1, and other A trace 114 does not have any openings H1. Therefore, the number and distribution of the openings H1 shown in FIG. 1A are merely illustrative and are not intended to limit the invention.

1C is a partial enlarged view of FIG. 1A, and FIG. 1D is a schematic cross-sectional view taken along line II-II of FIG. 1C, wherein FIG. 1C is an enlarged view of the overlap between the first trace 114 and the second trace 124. draw. Referring to FIG. 1C and FIG. 1D, at least one overlapping region Z1 (the oblique line region shown in FIG. 1C) is formed between the first trace 114 and the second trace 124. Taking FIG. 1C as an example, the overlapping area Z1 formed between the first trace 114 and the second trace 124 is two, and each overlap region Z1 is located between the opening H1 and one of the first side edges S1.

The opening H1 has a pair of first opening edges W1 and a pair of second opening edges W2. In the same opening H1, the first opening edges W1 are connected between the second opening edges W2, wherein the first opening edges W1 can be oriented in the same direction as the first side edges S1, and the second openings The course of the edge W2 can be identical to the course of the second side edges S2.

The second traces 124 located below the opening H1 have these second side edges S2 substantially aligned with the second opening edges W2. In detail, initially looking at one of the openings H1, it is understood that the second side edge S2 substantially overlaps the second opening edge W2 as shown in FIG. 1C. Therefore, the second trace 124 will substantially only overlap with the portion of the first trace 114 located between the opening H1 and the first side edges S1, and the overlap region Z1 will be limited to the second trace of the second trace 124. Between the two side edges S2.

Since each of the second traces 124 overlaps with one of the first traces 114, parasitic capacitance is inevitably generated at the overlap between the first traces 114 and the second traces 124. The parasitic capacitance causes the attenuation of the electrical signal, resulting in a decrease in the sensitivity of the touch sensing panel 100. The greater the capacitance of the parasitic capacitance, the greater the degree of sensitivity reduction.

However, since the second trace 124 is located directly below the opening H1, the opening H1 reduces the overlap area between the first trace 114 and the second trace 124, thereby reducing the capacitance value of the parasitic capacitance. In this way, the attenuation amplitude of the electrical signal can be reduced, thereby maintaining or improving the sensitivity of the touch sensing panel 100. Secondly, since the overlap region Z1 can be confined between the second second side edges S2 of the second trace 124, the overlap area between the first trace 114 and the second trace 124 is effectively reduced to improve the sensitivity.

In addition, the opening H1 can be freely designed. For example, the area of the opening H1 is increased such that the second side edge S2 can still substantially align with the second opening edge W2 under the condition that both the first trace 114 and the second trace 124 maintain a line width of sufficient width. As such, the present embodiment can reduce the overlapping area between the first trace 114 and the second trace 124 without substantially changing the resistance of the first trace 114 and the second trace 124, thereby maintaining or The sensitivity of the touch sensing panel 100 is improved.

2A is a top plan view of a touch sensing panel according to another embodiment of the present invention, and FIG. 2B is a cross-sectional view taken along line III-III of FIG. 2A. Referring to FIG. 2A and FIG. 2B , the touch sensing panel 200 and the touch sensing panel 100 of the present embodiment are similar in structure.

For example, the touch sensing panels 100 and 200 all include some identical components, and the components are the first sensing strip 110, the substrate 130, the insulating layer 140, and the protective layer 150. In addition, the advantages, functions, and applications of the touch sensing panels 200 and 100 are basically the same, so the description will not be repeated.

The touch sensing panel 200 includes a plurality of second sensing strips 220, and the difference between the touch sensing panels 200 and 100 is: a second trace 224 of each strip of second sensing strips 220. In detail, in the touch sensing panel 200, each of the second traces 224 has a pair of second side edges S4 opposite to each other, and the second side edges S4 of the same second trace 224 are located at Between the two second opening edges W2 of the opening H1, as shown in FIG. 2A.

Therefore, at least one overlapping area Z2 (the oblique line area shown in FIG. 2A) may be formed between the first trace 114 and the second trace 224, and the overlapping area Z2 is confined to the second side of the second trace 224. Between the edges S4. In this way, the overlapping area between the first trace 114 and the second trace 224 is reduced, thereby effectively improving the sensitivity of the touch sensing panel 200.

3A is a top plan view of a touch sensing panel according to another embodiment of the present invention, and FIG. 3B is a cross-sectional view taken along line IV-IV of FIG. 3A. Referring to FIG. 3A and FIG. 3B , the touch sensing panel 300 of the present embodiment includes a plurality of first sensing strips 310 , a plurality of second sensing strips 320 , a substrate 130 , an insulating layer 140 , and a protective layer 150 . . The structure of the touch sensing panels 100 and 300 is similar, but the difference is that the location of the first sensing strip 310 is different from the location of the first sensing strip 110, and the location of the second sensing strip 320 The position is different from the position of the second sensing strip 120.

Specifically, the first sensing strip 310 , the second sensing strip 320 and the insulating layer 140 are disposed above the plane 132 of the substrate 130 . However, unlike the touch sensing panel 100 , the first sensing strips 310 contact the plane 132 , and the insulating layer 140 covers the first sensing strip 310 and the plane 132 . The second sensing strip 320 is on the insulating layer 140 and above the first sensing strip 310. It can be seen that the insulating layer 140 is disposed between the first sensing strips 310 and the second sensing strips 320 , and the first sensing strips 310 are disposed between the insulating layer 140 and the substrate 130 .

The first sensing strips 310 and the second sensing strips 320 are staggered with each other. In FIG. 3A, the direction of the first sensing strips 310 is substantially perpendicular to the direction of the second sensing strips 320, wherein the extending direction of the second sensing strips 320 may be the horizontal direction X1, and the first sensing strips The direction in which the 310 extends may be the vertical direction X2. However, in other embodiments, the extending direction of the second sensing strip 320 may also be the vertical direction X2, and the extending direction of the first sensing strip 310 may also be the horizontal direction X1. Therefore, the extending direction of both the first sensing strip 310 and the second sensing strip 320 shown in FIG. 3A does not limit the present invention.

Each of the first sensing strips 310 includes a plurality of first sensing electrodes 312 and a plurality of first traces 314 , wherein each of the first traces 314 is connected between the adjacent two first sensing electrodes 312 . In detail, each of the first traces 314 has a pair of first side edges S5 opposite to each other, and the first side edges S5 connect the first sensing electrodes 312. In addition, the material of the first sensing electrode 312 may be the same as the material of the foregoing first sensing electrode 112, and the material of the first routing 314 may be the same as the material of the foregoing first routing 114.

Each of the second sensing strips 320 includes a plurality of second sensing electrodes 322 and a plurality of second traces 324 , wherein each of the second traces 324 is connected between the adjacent two second sensing electrodes 322 . In detail, each of the second traces 324 also has a pair of second side edges S6 opposite to each other, and these second side edges S6 connect the second sensing electrodes 322. In addition, the material of the second sensing electrode 322 may be the same as the material of the foregoing second sensing electrode 122, and the material of the second trace 324 may be the same as the material of the foregoing second trace 124.

These first sensing strips 310 will partially overlap these second sensing strips 320. In detail, as seen from FIG. 3A, each of the second traces 324 overlaps with one of the first traces 314, so the second traces 324 correspond to the first traces 314. However, each of the second sensing electrodes 322 does not overlap with any one of the first sensing electrodes 312, as shown in FIG. 3A.

In addition, each of the first traces 314 has an opening H2, and the second trace 324 is located directly above the opening H2. In the same first trace 314, the opening H2 is located between the first side edges S5, and the hole wall of the opening H2 is not connected to any first side edge S5, that is, the opening H2 is not from any first side edge S5 is extended.

It should be noted that although each of the first traces 314 shown in FIG. 3A has an opening H2, in other embodiments, only one or at least two of the first traces 314 may have an opening H2, and other A trace 314 does not have any openings H2. Therefore, the number and distribution of the openings H2 shown in FIG. 3A are merely illustrative and are not intended to limit the invention.

3C is a partially enlarged schematic view of FIG. 3A, and FIG. 3D is a cross-sectional view taken along line V-V of FIG. 3C, wherein FIG. 3C is an enlarged view of the overlap between the first trace 314 and the second trace 324. Referring to FIG. 3C and FIG. 3D, at least one overlapping region Z3 (the oblique line region shown in FIG. 3C) is formed between the first trace 314 and the second trace 324. Taking FIG. 3C as an example, the overlapping area Z3 formed between the first trace 314 and the second trace 324 is two, and each overlap area Z3 is located between the opening H2 and one of the first side edges S5.

The opening H2 has a pair of first opening edges W3 and a pair of second opening edges W4. In the same opening H2, the first opening edges W3 are connected between the second opening edges W4, wherein the first opening edges W3 can be oriented in the same direction as the first side edges S5, and the second openings The course of the edge W4 can be identical to the course of the second side edges S6.

The second traces 324 located above the opening H2 have these second side edges S6 substantially aligned with the second opening edges W4. Therefore, the second trace 324 will substantially only overlap with a portion of the first trace 314 located between the opening H2 and the first side edges S5, and the overlap region Z3 will be confined to the second trace of the second trace 324. Between the two side edges S6. As such, the area of overlap between the first trace 314 and the second trace 324 is reduced.

Although in the present embodiment, the second side edge S6 is substantially aligned with the second opening edge W4, in other embodiments, the second side edges S6 of the same second trace 324 may be located at the opening H2. Between the second opening edges W4, as shown in FIGS. 4A and 4B, the touch sensing panel 400.

4A is a top plan view of a touch sensing panel according to another embodiment of the present invention, and FIG. 4B is a cross-sectional view taken along line VI-VI of FIG. 4A. Referring to FIG. 4A and FIG. 4B , the touch sensing panels 400 and 300 are similar in structure. For example, the touch sensing panel 400 also includes a plurality of first sensing strips 310 , a substrate 130 , an insulating layer 140 , and a Protective layer 150. The difference between the touch sensing panels 400 and 300 is that the second trace 424 of the touch sensing panel 400 is touched.

The touch sensing panel 400 includes a plurality of second sensing strips 420 , and each of the second sensing strips 420 includes a plurality of second traces 424 . Each of the second traces 424 has a pair of second side edges S8 opposite each other, and the second side edges S8 of the same second traces 424 are located between the second second edge W4 of the opening H2. Each of the second traces 424 overlaps with one of the first traces 314 to form an overlap region Z4 (a diagonal region as shown in FIG. 4A).

Since the second side edges S8 of the same second trace 424 are located between the two second opening edges W4, the overlap region Z4 is confined between the second second side edges S8 of the second trace 424. As such, the area of overlap between the first trace 314 and the second trace 424 is reduced. In addition, it should be noted that the advantages, functions, and applications of the above touch sensing panels 300 and 400 are basically the same as those of the touch sensing panel 100, so the description will not be repeated.

In summary, in the touch sensing panel of the present invention, the opening of the first trace can reduce the overlapping area between the first trace and the second trace to reduce the capacitance value of the parasitic capacitance. As such, the present invention can reduce the attenuation amplitude of the electrical signal, thereby maintaining or improving the sensitivity of the touch sensing panel.
